Today I played a bit with Vortex86sx based device again. This time I wanted to get X11 working on it.
In short: it “works”. Default driver should be “sis” but it fails with messages which shows that libpciaccess has a problem on that device:
(EE) SIS(0): Unable to map IO aperture. Invalid argument (22)
(EE) SIS(0): **************************************************
(EE) SIS(0): ERROR:
(EE) SIS(0): Could not map MMIO area
(EE) SIS(0): END OF MESSAGE
(EE) SIS(0): **************************************************
(EE) SIS(0): **************************************************
(EE) SIS(0): ERROR:
(EE) SIS(0): SiSMapMem() failed
(EE) SIS(0): END OF MESSAGE
(EE) SIS(0): **************************************************
I switched to “vesa” driver — it works, gives 1280x1024 resolution. But it is so sluggish… Even my few years old Zaurus c760 is faster (I checked how Vortex86sx works with VGA resolution).
Tried also “fbdev” driver — same slowness. All was done with full X.org server not “kdrive” one.
